Hi everybody

I have a window project and use within a "ViewPort3D". It is include a UserControl using "ViewPort2DVisual3D" object and a "ModelVisual3D" object.

But I can't set animate "Opacity" with "EasingFunction" (in each KeyFrame) to "ViewPort2DVisual3D" + "ModelVisual3D".

In other words, "ViewPort2DVisual3D" not able to have "EasingFunction" in its KeyFrames, but "ModelVisual3D" have it.

How to set "EasingFunction" such as "bounces" effect on each KeyFrame and animate them (ViewPort2DVisual3D and ModelVisual3D) together in Expression Blend?

Please give me any your solution and ideas.
Thanks in advance.

Since the material of the Viewport2DVisual3D is the Visual that in it, you can put an UIElement as the Visual of the Viewport2DVisual3D and, animate the Opacity property of it.

For example, try the following Grid:

XML

<Grid Background="Blue">
    <Grid.Resources>
        <Storyboard x:Key="sb1">
            <DoubleAnimationUsingKeyFrames Storyboard.TargetName="grd1"
                                           Storyboard.TargetProperty="Opacity">
                <EasingDoubleKeyFrame Value="0"
                                      KeyTime="0:0:0.5">
                    <EasingDoubleKeyFrame.EasingFunction>
                        <BounceEase />
                    </EasingDoubleKeyFrame.EasingFunction>
                </EasingDoubleKeyFrame>
                <EasingDoubleKeyFrame Value="1"
                                      KeyTime="0:0:1">
                    <EasingDoubleKeyFrame.EasingFunction>
                        <BounceEase />
                    </EasingDoubleKeyFrame.EasingFunction>
                </EasingDoubleKeyFrame>
            </DoubleAnimationUsingKeyFrames>
        </Storyboard>
